    Running total in VB

    Hi,

    Im trying to keep a running total within a text box. The code I am using is
    Code:
       RunningTotal.Text = Txtbox1.Text + RunningTotal.Text
    WHen I do this, RunningTotal.text only adds the content from txtbox1 onto the end, so I end up with something like " 1.50, 1.50". Every time I hit Add, i just get another 1.5o added onto the end of the existing 1.50, 1.50.

    Thanks

    Those results are correct. + when used with strings is the same as & (concatenate).
    Read about TryParse, ToString, and Convert.

    Val would be my last choice, especially for user input.
